Introduction
UART Fingerprint Reader is a new fingerprint development module dedicated to secondary development and integrated applications, with high speed, fast identification and high stability.
The UART Fingerprint Reader module takes the STM32F205 high-speed digital processor as the core, combines commercial fingerprint algorithms, high-precision optical sensors, and is an intelligent type with functions such as fingerprint entry, image processing, feature value extraction, template generation, template storage, fingerprint comparison, and search. Module; provides UART interface and communication protocol, specially provides standard secondary development fingerprint kits for scientific research units and application integration manufacturers, which is fast and easy to integrate applications!
Feature
The fingerprint sensor is sensitive and the recognition speed is fast:the fingerprint module uses a high-precision optical path and imaging element. When using it, you only need a finger to lightly recognize it.
Strong stability:using ST’s STM32F205 advanced digital processing chip as a processor, low power consumption, fast and stable, at least 30% more stable than domestic chips and chips of other platforms.
Scientific structure:using split structure, fingerprint sensor + processing motherboard + algorithm platform, the motherboard is stable;
Use standard 16P universal interface; the sensor can independently choose and replace optical and semiconductor sensors;
Using commercial algorithms, fast.
Easy to develop:serial UART operation (connect directly to any microcontroller with a serial port), simple operation, and equipped with PC demo, learning software, related tools and microcontroller routines.
Open:You can freely input and output fingerprint pictures, fingerprint feature value files and various fingerprint operations. The protocol is more complete and the opening is better.
Applications
Fingerprint product development:development of fingerprint lock, fingerprint safe, fingerprint access control, fingerprint attendance
Fingerprint integration application:development of fingerprint locks, integrated in various security products, such as intercom, switch, personnel identification, authority management
